XIANUI Deep Vitamin C Radiance Serum – 5% Niacinamide, TXA & Triple Hyaluronic Acid, 1.01 fl oz — Brightening Hydrating Face Serum

XIANUI Deep Vitamin C Radiance Serum is a lightweight daily serum that brightens, hydrates, and helps even skin tone using a four-way radiance complex and triple hyaluronic acids.

This serum blends 5% niacinamide, tranexamic acid (TXA), glutathione, and a stable 3-O-ethyl vitamin C with a licorice-root calming base to support a clearer-looking, more luminous complexion. Ceramide NP, squalane, and three forms of hyaluronic acid reinforce the skin barrier and deliver multi-layer hydration while a silky, non-sticky texture makes it easy to layer under moisturizers and sunscreen.

How does this serum help dull or uneven-looking skin?

The product targets visible dullness and uneven tone with a balanced brightening complex designed for daily use. It combines niacinamide and TXA to help the look of discoloration while glutathione and the ethylated vitamin C work to support surface radiance.

• 5% niacinamide to promote an even-looking texture and tone.
• Tranexamic acid (TXA) supports reduced appearance of dark spots.
• Glutathione plus 3-O-ethyl vitamin C for stable antioxidant support.
• Licorice-root extract soothes skin during brightening.

Will it hydrate and strengthen the skin barrier?

Yes — the formula includes barrier-repairing and hydrating lipids to restore resilience and plumpness. Multiple hyaluronic acid forms reach different skin layers while ceramide NP and squalane replenish lipids for a softer feel and reduced moisture loss.

• Triple hyaluronic acids (sodium hyaluronate, hydrolyzed HA, acetylated HA) for multi-depth hydration.
• Ceramide NP to support barrier structure and comfort.
• Squalane for lightweight, lasting emollience.

Is this serum suitable for sensitive or reactive skin?

The base uses licorice root and omits artificial fragrance and harsh preservatives to lower irritation risk. Dermatologist-tested for low irritation, the serum is formulated to be gentle while delivering active brightening and hydration ingredients.

• Fragrance-free formula to reduce sensitivity triggers.
• Licorice-root extract to help soothe and calm.
• Dermatologist-tested and chosen ingredients for purity and tolerance.

How does the texture feel and how do I layer it?

The serum absorbs quickly with a silky, non-sticky finish that makes layering simple. Apply a few drops to clean skin, follow with moisturizer, and use sunscreen by day to protect results and maintain radiance.

• Lightweight, fast-absorbing texture—no greasy residue.
• Designed for daily morning and/or evening application.
• Works easily under moisturizers and SPF without pilling.

Who this is for: XIANUI Deep Vitamin C Radiance Serum suits anyone seeking brighter-looking, more hydrated skin without heavy or irritating formulas — especially those with dullness, uneven tone, or anyone who prefers fragrance-free, dermatologist-tested actives. Its combination of gentle soothing ingredients, barrier-repair lipids, and multi-depth humectants makes it a practical daily step for all skin types, including sensitive and reactive skin.
